Application filed Ju1y 18, 1924, serial to.

This invention relates to an attachment for driving wheels of motor vehiclesto ena ble the same to negotiate bogs or sandy country without assistance, theobject of s e curved plate K and flattened end K," the which is to provide means for'travelling in bad country without chains or other devices fixed to the tires of the wheels which 7 are liable to injure the same; I

The invention consists of two concentric metal rings connected together by square or" T section metal spokes forming a skeleton wheel. The inner ringis fitted round the hub of the motor vehicle wheel and the to which it pleasure.

To each'ofthe spokes ofithe skeleton wheel are suitably fasteneddetachable and 5 adjustable paddles which when travellingin boggy orsandy country grip the road.

The invention consists of a number of detachable T 1I'0I1 or steel carr1ers,1 the number depending upon the size of the motor:

wheel. The outer ends of these carriers are formed integrally with curved plates adapt-p ed to be bolted to'the' rim of the motor wheel and at their inner ends the web iscut away, their ends flattened and provided with holes for bolting sameon to the hub of the motor wheel. r v

The web of the'carrie'rs is providedwith a series of holes which allows the paddles to be bolted thereto indifferent positions according. to requirements.

To fully describe the invention reference is now made to'the accompanying drawings in which s v F ig. 1 is an elevation of a motor wheel showing paddles attached to the carriers in different positions. I v V Fig. 2 is a plan view of a detachable carrier. I V

Fig. 3 is a side elevation of the same. Fig. 4: is a front view of the paddle.

Fig. 5 is an end view from the leftside. Q Fi 6 is an end'view from theright side and illustrating the flange.

Fig. 7 is an endview ofa coupling block.

.F the hub' 'of the wheel.

Referring to the drawing D is the rim to of "the motor. wheel, E the rubber tire and K are the carriers formed integrally with latter being bolted to the hub of the wheel strengthened by flanges L- and recessed at the heelfor fitting onto the carrier K; M

is a coupling block recessed in a' similar? manner as the heel of L; bracketlL and block M being fastened bvbolts. The earrier K is formed with flanges-L and these jpaddles are bolted in required position to the web of the carriers by the coupling The advantages of the invention are: that in operation it packs the soil under or be- I hind thejblades'on a track outside and gdisa 70.

tinct from that taken bythe wheels of the vehicle. and; thereforethe wheels have no tendency. to dig themselves further into the ground;;clogging orchoking by mud is tached from motor vehicle wheels without prevented; c'aneasily be attached or de- 1 removing same and the tires are notsub- A of other devices attached to the tires.

jected to anvadditional wear as in the use The invention as herein described, whilst obtaining the. desired object may be varied in details of constructionwithout departing from the spirit of the invention as expressed in the claims.

What I claim a'siny invention, and desire, Y

to secure by Letters Patent is In improvements in attachments for motor vehicle wheels, carriers formed integrally with an arcuate head adapted to bolt on I i to the rim of the wheel, said carriers formed with flattened-ends adapted to bolt on to the hub of the wheel'and'a central longi-' ,tudinal web bored for. adjustably attaching thereto paddles as and forthe purpose set forth and as herein substantially .de-

In testimony whereof I have signed my scribed. 1
